Mushkin Enhanced MSL4U213FF4G18 4GB DDR4 2133MHz CL15 1.5V desktop RAM

Capacity and fit

This 4 GB DDR4 DIMM runs at 2133 MHz with a CAS latency of 15 and a 1.5 V operating voltage. The unbuffered, non-ECC design uses a standard 240-pin layout for desktop motherboards that accept PC4-17000 modules. It suits basic office PCs, light content-consumption rigs or repair jobs where a single low-density stick is required. Buyers needing higher capacities or multi-channel kits should look elsewhere.

Thermals noise and power

At the rated 1.5 V the module draws modest power and generates little heat during typical desktop workloads. No active cooling is included or required; passive airflow inside a normal case is sufficient. The stick runs silently because it has no moving parts. Power draw scales with actual memory activity rather than sitting at a fixed high level.
